[PATCH v2] kernel/modsign_certificate.S: use real contents insteadof macro GLOBAL()

From: Chen Gang
Date: Mon Oct 28 2013 - 22:19:08 EST

If a macro is only used within 2 times, and also its contents are
within 2 lines, recommend to expand it to shrink code line.

For our case, the macro is not portable either: some architectures'
assembler may use another character to mark newline in a macro (e.g.
'`' for arc), which will cause issue (e.g. arc with allmodconfig):

LD init/built-in.o
kernel/built-in.o: In function `load_module_signing_keys':
kernel/modsign_pubkey.c:66: undefined reference to `modsign_certificate_list'
kernel/modsign_pubkey.c:71: undefined reference to `modsign_certificate_list_end'
kernel/modsign_pubkey.c:67: undefined reference to `modsign_certificate_list_end'

If still want to use macro and let it portable enough, it will need
additional line -- include additional header file (e.g "#include
<linux/linkage.h>", although it also need be fixed).
